Turn sync on and off in Chrome

When you sync

You'll sign in automatically to Gmail, YouTube, Search, and other Google services. If you were signed in before turning on sync, you'll stay signed in.

If you change devices (like if you lose your phone or get a new laptop), you'll get your synced info back.

You’ll personalize your experience in other Google products by including your Chrome history if you turn on Web & App Activity.

Chrome may combine any declared age and gender information from your Google account with our statistics to help us build products better suited for all demographics. This information does not personally identify you and is used only in aggregate form.

Important: Only turn on Chrome sync with devices you own. If you're using a public computer, use guest mode instead.
